LOOP CLOSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 370,143, dated September 20, 1887.

(No model.)

19 rod or part of the article to which the loop is to be attached.

The object of my invention is to automatically carry the articles with the open loops in dies successively under a die for closing the loops; also, to automatically discharge from the machine the article with the loop thereto attached.

In the drawings forming a partof this specification, Figure l is a plan of the machine.

Fig. 2 is a vertical crosssection of the same.

Fig. 3 represents a side view of the discharging device; Fig. 4, a like view of the part which operates the latter, and Fig. 5 a like view of parts operating the carrier.

The carrier a is formed with a series of dieseats, a, to receive aseries of dies, a, in which are placed rings a and stud a, to be operated upon. Other articles of various shapes and for different purposes requiring a looped staple or tongue to be attached may be placed in dies a, the latter being suitably formed to receive the articles.

The carrier a is supported by frame f and intermittently rotated by means of ratchet 0 Its hollow shaft 1) rotates on stud e, formed with circular flange e, resting on frame f and held by nut 0 The carrier may be removed from stud c and a different one put inits place on taking off the upper nut, e, The frame is formed with a slot, (1, in which stud e is adjustable by means of thumb-screw k. Shaft b rotates in a friction-collar, Z, having a lining, Z, of leather or other suitable material, and

4 5 adjustable by means of thumb-screw Z" to prevent any farther forward motion of the carrier a than that of pawl c. Collar Z is kept from turning by set-screws o 0, turned against flange e of stud e. Lever b carries die 0 and It is provided with a slotted bar, '1', which operates crank-shaft a, arm 0, and finger a, thereto at tached, for the purpose of discharging from die a, the article to which the loop has been closed by die 0 the point of the finger lifting and throwing the article or ring (6 from die a. The finger is adjustable on arm 0 by means of slide M, to which itis hinged. Thefinger may be connected directly with shaft a; but Iprefer the intermediate arm, 0, in order to provide it with a spring, 8, to guard the finger against strain or injury while it is moving back to the position shown in the drawings. Each die a is grooved for the passage of finger a through it. Crank-shaft it rocks in and is supported by arm m, bolted to frame f. Die 0 is suitably formed and adapted to turn down or close the open loop. \Vhen die 0 is descending to close a loop, finger it removes from one of the dies a an article already operated on, and at the same time pawl c is drawn back on ratchet c. \Vhen die 0 is ascending, finger it returns to the position shown in the drawings, and pawl 0 turns carrier a to bring its next following dies a under die 0* and finger a, respectively. Pawl 0 should be so adusted that it will not turn carrier a until finger a has returned through the grooved die a; but if not so adjusted springs s willenablethe finger to pass over the die.

It is obvious that more than one die 0 and a like number of fingers a may be used, so that two or more articles or loops may be operated simultaneously. The curvilinear motion of the forming-die 0 being eccentric to the eye of the loop, aids in properly closing the latter.

An endless apron, av'erticall y-rotatin g wheel, or other form of carrier having intermittent motion may be used instead of the horizontal disk a; but I prefer the latter.

I claim as my invention 1. In a loop-closing machine, a die-carrier having intermittent motion and formed or provided with a series of dies adapted to receive and hold a stud or tongue having an open loop, and a vibrating arm or lever formed or provided with a die, this die describing a curvilinear motion toward and from the dies in said series successively and operating eccentric t0 the eye of said loops to close them, substantially as described.

U with and both operated by lever b, substantially as described.

5. The die-carrier a, ratchet c, pawl 0, die 0 crank-shaft n, and finger n, in combination with and all operated by lever b, substantially as described.

6. Lever 1), formed or provided with slotted bard, in combination with crank-shaft n and a discharging-finger, substantially as described.

7. The finger n, in combination with arm 0, slide n spring 8, and crank-shaft n, substantial] y as described.

8. The die-carrier a, formed or provided with hollow hub b, in combination with stud 6, formed with flange e and provided with nuts 6 6 substantially as described.

9. The die carrier a, formed or provided with hollow shaft b, in combination with stud 6, formed with flange e and provided with nuts 6 6 and fricti0n-col1ar land screw 1 substantially as described.

10. The die-carrier a, having hollow hub b. in combination with stud 6, frame f, formed with slot d, and adj usting-screw is, substantially as described.
